Via unfogged, the NYT looks at American school systems that, in response to well-documented slumps in performance for kids at middle school age, are trying alternative arrangements. For some, the best approch is to put the youngsters in wiht high schoolers; for others, it's to turn lower school into K-8.
Re the former, more common approach:
Researchers at Johns Hopkins University
found that students at Philadelphia’s established K-8 schools
outperformed students at traditional middle schools, but that those
schools had fewer poor and minority students and more experienced
teachers, which could have largely explained the results.
In
Philadelphia’s newer K-8s, which are more similar demographically to
the city’s middle schools, students performed slightly better than at
middle schools, but those advantages were not always statistically
significant.
Re creating 6-12 schools, the key focus appears to be to give the principal and teachers more time to prepare the kids to succeed in life, preferably by getting into uni. A lot of this seems to be based on getting kids when they're young enough to successfully adapt to an ambitious, disciplined school ethos.
The 6th- through 12th-grade school is less common, and less studied.
In New York City, where such schools have proliferated — 38 have opened
since 2002 — the shift is being driven largely by nonprofit
organizations that have helped start new, small schools. These schools
are under pressure to show they can produce better results than
traditional ones.
In many ways these schools were conceived
less as a solution to the middle school problem than as solutions to
the high school problem — that is, the problem of having just four
years to work magic with woefully underprepared freshmen.
This is interesting:
Both 6-12 and K-8 schools eliminate one transition from students’
lives. Both also tend to have far fewer sixth- through eighth-grade
students than the typical middle school — a difference that those who
work with middle school students say cannot be underestimated.
“One
middle school student is like three high school students in terms of
their behavioral needs and the issues you’re confronted with,” said
Fred Walsh, principal of the School for International Studies in Cobble
Hill, Brooklyn.
In either case, I would agree that 11 is a challenging age to be making a transition from one sort of school to another - while on the other hand I can see the arguments for putting kids into ambitious settings younger.
